“Sometime in 2012, however, AMD will likely release a new, more powerful CPU core and pair that with one of its GPUs. If Apple is going to consider moving any of its products to AMD, that would be the time. Apple and AMD have been discussing Fusion over the past couple of years. Whether or not it’s simply to keep Apple’s options open is up for debate at this point. I guess we’ll find out in 2012”
Or there is the other option.
Apple likes what they see. Buy AMD for $8bln and then swtiches. They’ll then own almost all the value in their Macs.
